Kim Jong Un claimed his regime's missile program is a necessary deterrent amid continuing threats from external forces.

Analysts in Seoul have expressed growing concern that both political parties competing for the presidency in the U.S. may shift away from the long-standing goal of denuclearizing Pyongyang.
